T0 00 whom it may concern:

Be it known that I, CHARLES DUMKE, of Portland, in the county of Dodge and State of 'Wisconsin, have invented a new and useful Improvement in Vehicles, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

My invention relates to improvements in vehicles, and it pertains to the construction of the bolster and the king-bolt and the axle or beam, with which they are connected, and related devices, the object of the invention being to strengthen the bolster by obviating the necessity for passing the king-bolt through it, and also for so constructing the king-bolt and connecting it with the axle or beam to which the bolster is secured as to lock the bolster removably in place on the axle or beam that supports it.

In the drawings, Figure 1 is a front elevation of a bolster, a portion of an axle, the intermediate cross-bar, and the king-bolt, parts being broken away to show interior construction. Fig. 2 is a vertical transverse section on line 2 2 of Fig. 1. Fig. 3 is a detail of the axle-plate. Fig. 4: is an elevation of a modified form of device, showing a bolster connected directly to the beam of a sled.

In the drawings, A is the axle, B B the ton guehounds, O the cross-bar, and E is the bolster, of a wagon in which my improved form of construction is embodied, the parts already enumerated being in their general form such as are in common use.

It is common to insert a king-bolt through the bolster from its top surface, which kingbolt extends down through the cross-bar and throughthe axle. Such a form of construction is objectionable, in that as the king-bolt is usually made of considerable size a large aperture is required through the bolster and through the axle for the king-bolt, which aperture weakens the bolster and also the axle very considerably.

In my improved device the king-bolt F is secured to the bolster E by means of a plate G, which plate is secured removably against the under surface of the bolster by means of the bolts H H. The king-bolt F is passed through the plate G from its upper side, the head of the boltbeing preferably let into the upper surface of the plate, whereby, as the head of the boltis square, elongated, or faced on one side and is fitted into a recess therefor in the plate, the bolt is held in position against revoluble motion. The plate G serves also as a bearing-plate resting on the plate I, secured to the top surface of the crossbar O by the bolts K K passing through the plate, through the cross-bar O, and through the axle A. The plate G is also preferably provided with an annular flange L about the king-bolt, which enters a circular aperture therefor in the plate F, the annular flange serving as a bearing against the plate F to prevent horizontal motion of the bolster E. The bolts K K also pass through a plate M, thereby secured rigidly to the axle A, there being sleeves N N about the bolts K, which hear at their ends against the cross-bar O and against the top of the plate M, holding it rigidly in position against the axle A. i

The king-bolt F passes through the crossbar 0 and through the reach 0, and its lower extremity passes through the plate M in an aperture P therefor. The lower end of the king-bolt is provided with a lug or lateral projection R at one side, which is fitted and adapted to pass through the laterally-extending part P of the aperture P when the king-bolt is in proper position therefor, and when the kingbolt is thereupon turned either to right or left a part of a revolution locks the bolster revolubly to the axle. It will be understood that by this form of construction when the bolster is placed above the cross-bar O and the kingbolt is passed downwardly through the crossbar, through the reach, and into the plate M, the lug R passing through the laterallyextended part P of the aperture P, thereupon, if the bolster is swung around the onelialf of a revolution, the bolster will be held against raising off the axle or permitting the king-bolt to be withdrawn from the reach by means of the lug R engaging against the un der surface of the plate M. Also it will be seen that this form of construction obviates the making an aperture for the king-bolt through the bolster and also obviates an aperture through the axle.

In the modified form of device shown in Fig. 4 a sleigh-beam S is shown instead of an axle A, which is provided with an upper bearing-plate T and a lower plate T, the plate T being provided with an aperture like the aperture P in the plate M, having alateral extension P for the passage therethrough of the lug R on the king-bolt. In this form of device there is no interposed cross-bar between the bolster and the beam, and the reach U is let into the beam S in a slot therefor and the king-bolt passes through the end of the reach.

What I claim as new, and desire to secure by Letters Patent, is-

In a vehicle, the combination, with a bolster E and a king-bolt F, secured rigidly to the bolster by a plate G, secured to the bolster by bolts H H, the plate being provided with a socket in its u er surface, into which the head of the bolt is received and held against rotation and having a laterally-pro-
